Hello, I watch your educational videos very informative thank you. I?m 53, I take TRT for 10 years and now just started using MK677. I?m interested in YK 11. In your video you mention YK 11 may have libido issues, I?m 53 dude I do not want libido issues. I?d like to definitely get stronger and make some good gains I take it estrogen blocker. And if I was to use YK 11 in a slow and low sensible manner do you think the side effects are something to be concerned about
